Stability of two-mode internal resonance in a nonlinear oscillator
(Springer, 2018-05)
We analyze the stability of synchronized periodic motion for two coupled oscillators, representing two interacting oscillation modes in a nonlinear vibrating beam. The main oscillation mode is governed by the forced Duffing ...
Instabilities of spin torque driven auto-oscillations of a ferromagnetic disk magnetized in plane
(Amer Physical Soc., 2016)
The stability of the magnetization auto-oscillations of the ferromagnetic free layer of a cylindrical nanopillar structure is studied theoretically using a classical Hamiltonian formalism for weakly interacting nonlinear ...
Spin wave modes of two magnetostatic coupled spin transfer torque nano-oscillators
(American Institute of Physics Inc., 2018)
A detailed analytical and numerical study of the spin wave modes of two nanopillar spin torque nano-oscillators coupled by magnetostatic interactions is presented under the macrospin approximation. Results show that the ...
Principal modes and related frequencies of sea surface temperature variability in the Pacific coast of North America
(Journal of Oceanography, 2003)
We examined monthly time-series (1950 to 1999) of sea surface temperature (SST) anomalies in 47 quadrants (2° 2°) along the Pacific coast of North America. Correlation, clustering and principal components analyses were ...
Mode-locked Bloch oscillations in a ring cavity
(Institute of Physics - IOPBristol, 2014-12)
We present a new technique for stabilizing and monitoring Bloch oscillations of ultracold atoms in an optical lattice under the action of a constant external force. In the proposed scheme, the atoms also interact with a ...
Collective modes of coupled phase oscillators with delayed coupling
(American Physical Society, 2012-04)
We study the effects of delayed coupling on timing and pattern formation in spatially extended systems of dynamic oscillators. Starting from a discrete lattice of coupled oscillators, we derive a generic continuum theory ...
Floquet stability analysis of the flow around an oscillating cylinder
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
This investigative work is concerned with the flow around a circular cylinder submitted to forced transverse oscillations. The goal is to investigate how the transition to turbulence is initiated in the wake for cases with ...
